Description
Technical field
The utility model belongs to power cable technical field, is specifically related to a kind of high filling high water resistant cable.
Background technology
Along with national development, electric power system and traffic system are also at high speed development, and cable is widely used in harbour, tunnel, the places such as hydraulic engineering; South rainy climate condition is changeable, and how unstable cable works in a humidity environment, and the work wanting cable stable must strengthen the block-water effect to cable.Traditional cable water preventing ability is poor, along with cable gradually aging moisture can penetrate into insulating barrier gradually, make increase maintenance difficulty and security risk.
The primary structure of present cable is made up of cable core and sheath, core cross section is mostly circular, there is space by between the core that stranding is adjacent, because space can affect the compactness of the construction of cable, when using for a long time or be subject to extraneous extruding, cable can be made to deform.
Therefore, how improving the block-water effect of cable, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The utility model provides a kind of high filling high water resistant cable, has good water preventing ability, and extends the useful life of cable.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of high filling high water resistant cable, comprise cable core and be coated on the protective jacket outside described cable core, described cable core is the conductor that some electric units are intertwined, described electric unit comprises metal bare wire, is coated on waterstop outside described metal bare wire and ethylene propylene rubber insulated layer successively from inside to outside, described protective jacket is haloflex oversheath, is provided with crosslinked polyethylene watertight composition between described cable core and protective jacket.Cable core is wound along with electric unit, waterstop forms the horizontal water proof that blocks water, and between cable core and protective jacket, also have the crosslinked polyethylene watertight composition longitudinally arranged, form longitudinal water proof that blocks water, whole cable is made to have multiple block-water effect, can reach vertical, horizontal two-way water-resistant, greatly strengthen the block-water effect of cable.
Haloflex (CPE) can not decompose when normally using and storing.It has two kinds of typical structures, and one is that chlorine atom is random and be uniformly distributed on macromolecular chain, becomes saturated elastomer; Two is chlorine atom random block distributed unevenly on macromolecular chain, shows the behavior of duroplasts.The haloflex of chlorinty 25%-45% is the specific rubber of a kind of heat-resisting, weathering and resistance to combustion, has self-extinguishment.The haloflex of chlorinty more than 45% is white uniformity graininess amorphous solid.Along with the replacement of chlorine, destroy poly crystallinity, vitrification point is reduced, but after exceeding certain chlorinity, vitrification point raises again.Due to the introducing of the saturated chlorine atom of macromolecular structure, CPE is made to have good pliability, ozone resistance, weather resisteant, heat-resistant aging, oil resistance, anti-flammability, electrical property, chemical proofing.Elasticity and cold resistance are slightly poor.It also has the ability of very high accommodation filler.Adopt CPE as protective jacket, there is Cold-resistant anti-corrosion effect, the combination property of cable can be improved, for cable core provides excellent protective value, effectively extend the physical life of cable.
Preferably, steel band is provided with between described crosslinked polyethylene watertight composition and protective jacket.Effectively can stop biological the baiting and destroy such as mouse ant, protect the complete of internal structure and safety, crushing resistance can be improved simultaneously, ensure that inner cable core normally works.
Preferably, described steel band is double plastic-coated steel band.
Preferably, the space between the space between described cable core and crosslinked polyethylene watertight composition, electric unit is all filled with flexible polyurethane foams, is also provided with fire-proof heat-insulating reinforcement in the space between electric unit.Flexible polyurethane foams is adopted to fill, form the soft right foam matter packed layer of plasticity, inner structure is more compacted, even if be subject to extraneous extruding, cable also can remain unchanged shape, and flexible polyurethane foams to have water absorption high, the characteristic that water preventing ability is excellent, the moisture that seepage is come in can be absorbed, ensure that internal structure is dry.
Preferably, described fire-proof heat-insulating reinforcement is glass fibre belt.Glass fiber tape adopts high-temperature-resistant high type glass fibre, processes through special process.There is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, the feature such as weatherability, high strength, smooth in appearance.Spun-glass insulation heat insulating belt, silicon rubber glass fibre is mainly divided into protect heat insulating belt, glass radiation proof heat-preserving heat-insulating belt etc.
The utility model discloses a kind of high filling high water resistant cable, adopt multilayer stop water, obtain longitudinal and transverse two-way water-resistant effect, the block-water performance of cable is increased substantially, and adopts flexible polyurethane foams to fill, inner structure is more compacted, even if be subject to extraneous extruding, cable also can remain unchanged shape, can absorb the moisture that seepage is come in, and ensures that internal structure is dry.Adopt haloflex oversheath as protective jacket, there is Cold-resistant anti-corrosion effect, the combination property of cable can be improved, for cable core provides excellent protective value, effectively extend the physical life of cable.
